Yes, the Graffiato vehicle is a strange phenomenon: a food truck that’s not a food truck, but calls itself a food truck and parks in the same high-traffic squares as other, real-life food trucks. People even line up for it, but for ...what? Free T-shirts? Small samples of a single dish that’s not even on the Graffiato menu? A tasting contest? A chance to tap on the glass and gawk at the celebrity chef, like a visit to the Small Mammal House at the National Zoo?

All of the above, I suspect.

Whatever you call Isabella’s ceremonial parade around the city today, it attracted a lot of attention. Check out some photos after the jump.
